Temperature Sender

Does anyone know how the temp. sender works. Is it a resistive type
that decreases resistance as the temp. goes up or is it a switch that
closes at a set temperature? I removed the sender from the exhaust
manifold and tested it with a voltmeter. I found it to have no
conductivity when cold.

Thanks

If the temperature gets too high it will close and creates a connection to engine body (negative/mass). if you take the wire leading to the sender and put it against a metal part of the engine the temperature warning light should go on.
